While playing this morning I had the same issue. However it happened to me while playing online. When i turn on the game I am a level 34 like i should be but as soon as i begin playing a multiplayer game I reset to a SR 1 . I spoke to a lady at microsoft and she said to try saving it on the cloud as opposed to harddrive. She said she can't tell me when it will be fixed. I wish we could get some kind of armor or something for having to deal with this junk.
